NodeJS 11.x
curl -sL https://rpm.nodesource.com/setup_11.x | bash -
NodeJS 10.x
curl -sL https://rpm.nodesource.com/setup_10.x | bash -

Optional: install build tools
To compile and install native addons from npm you may also need to install build tools:
yum install gcc-c++ make
# or: yum groupinstall 'Development Tools'
Then install:
sudo yum -y install nodejs
